The present invention relates to a crusher, and more particularly, to a crusher for crushing the crushed material such as minerals, rocks, aggregates, construction waste, etc. put into the size suitable for the purpose of use.

Generally, a device for crushing original crushed materials such as relatively large-scale minerals, rocks, aggregates, construction waste, etc. to a size suitable for the purpose of use, for example, jaw crusher and hammer crusher Shredders are used.

In a crushing process using a conventional crusher such as a jaw crusher and a hammer crusher, since the size of the crushed material cannot be drastically reduced in size, the size of the crushed material is gradually reduced by a multi-step crushing process. A method is used, one embodiment of such a conventional shredding process is schematically illustrated in FIG.

As shown in Figure 1, in the case of crushing the original shredding material such as minerals, rocks, aggregates, construction waste, etc. of a relatively large size to a size suitable for the purpose of use, for example, the original shredding material to a predetermined size Primary crushing process to crush, secondary crushing process to crush the crushed material after the primary crushing again and again to a smaller size, the third crushing of the crushed material subjected to the second crushing process to a smaller size A crushing process, a crushing material subjected to the third crushing process must be subjected to a multi-stage crushing process, such as a fourth crushing process to finally crushed to a smaller size suitable for the purpose of use.

In the conventional crushing process as described above, since the original crushing material such as minerals, rocks, aggregates, construction wastes, etc. of a relatively large size must be crushed to a size suitable for the purpose of use, the time required for the crushing process must be continuously It is very long, because the multi-stage process equipment must be arranged continuously, it is expensive and there is a problem that the installation area of the process equipment is very large.

Therefore, in the present invention, in crushing the original crushed material such as mineral, rock, aggregate, construction waste, etc. of relatively large size to a size suitable for the purpose of use, significantly reducing the time and cost and at the same time installing process equipment It is based on the problem of providing a crusher that can significantly reduce the area.

The problem is solved by the shredder according to the present invention, the shredding material such as minerals, rocks, aggregates, construction waste, etc. to be shredded to a size suitable for the purpose of use by only one process and equipment using the principle of soft mill.

One end of the horizontal support 37 is fixed to the vertical rotation shaft 31 by a fixing member 35 such as a hinge pin, for example, and two horizontal supports are formed at intervals of 180 degrees from each other. desirable.

The soft stone 41 is rotatably supported by the soft stone support bearing 43 on the horizontal support 37, and the soft stone 41 is rotated by the vertical rotation shaft 31. Rotating on) serves to crush the crushing member on the bottom plate portion 20, especially the mesh plate 25. The soft stone 41 is preferably formed of granite or heavy steel in order to break up crushed materials such as minerals, rocks, aggregates, construction waste, and the like.

In addition, the soft stone 41 is inclined outward from the stationary state by the gap of the soft stone support bearing 43 so as to be rotatably supported on the horizontal support 37 and vertically by inertial force at high speed rotation. It is preferable to be.

The flagpole 45 is integrally extended to the lower portion of the vertical axis of rotation 31, and the outer side of the flagpole 45 in the radial direction to collect the crushed material on the base plate portion 21 in the direction of the soft stone 41. The outer feather 47 bent toward the inside is provided, the soft stone (41) to collect the crushed material on the central base plate portion 21b in the radial direction of the flagpole 45 in the direction of the soft stone (41) The inner feather 49 is bent toward.

Here, the flagpole 45 is preferably at right angles to the horizontal support (37), preferably two extend beyond the mesh plate 25 to the base plate portion 21.

The outer feather 47 serves to collect the crushed material on the base plate portion 21 in the direction of the soft stone 41, the shape of the outer feather 47 is concave toward the inside as a whole, radially The outer end is bent in the inner direction and the inner end in the radial direction is bent toward the soft stone 41, thereby scraping the crushing member on the outer base plate portion 21a during the rotation of the flagpole 45 to form an inner mesh plate 25. It is preferred that it is easy to transfer to the phase.

The inner blade 49 serves to collect the crushed material on the central base plate portion 21b in the direction of the soft stone 41. The inner blade 49 has a radius, as shown in FIG. The outer end in the direction is bent toward the soft stone 41, and the inner end in the radial direction is bent in the direction of the vertical rotation shaft 31, thereby scraping the crushing member on the central base plate portion 21b to form an outer mesh plate ( 25) It is preferred that it is easy to be transported onto the bed.

Hereinafter, the overall operation of the shredder 1 according to an embodiment of the present invention will be described in detail.

First, in a state in which crushed materials such as minerals, rocks, aggregates and construction wastes are introduced into the main body portion 10 through the inlet 11 and placed on the bottom plate 20, the power of the power source is a power transmission mechanism. When the 33 is transmitted to the vertical rotation shaft 31 through a bevel gear system or a combination of a belt and a pulley, the vertical rotation shaft 31 has both ends of the power transmission mechanism 33 and the central base plate portion 21b. Supported by the central hole 27 is rotated in a vertical state from the center in the body portion 10.

When the vertical axis of rotation 31 is rotated, the horizontal support 37, one end of which is fixed to the vertical axis of rotation 31 is rotated together, thus the soft stone is rotatably fixed on the horizontal support (37) As the 41 is rotated, it is engaged with the crushed material on the mesh plate 25, and the crushed material is crushed by the load and friction of the soft stone.

The shredding members which are crushed down to the diameter of the mesh hole 27 formed in the mesh plate 25 are passed through the mesh hole and sent to the sorting device (not shown) such as a vibrating screen through the outlet 13. In the sorting device, the sorting is carried out according to its size.

When the vertical axis of rotation 31 is rotated, the flagpole 45, one end of which is fixed to the vertical axis of rotation 31 is also rotated, and as the flagpole 45 rotates, the radius of the flagpole 45 The shredding members located on the outer base plate portion 21a by the outer feathers 47 fixed to the outside in the direction are collected on the mesh plate 25 and are broken by the soft stone 41, and the flagpole The shredding members located on the central base plate portion 21b by the inner blade 49 fixed to the inner side in the radial direction of the 45 are also collected on the mesh plate 25 and formed by the soft stone 41. Crushed.

The movement of the shredding members onto the mesh plate 25 by the vanes 47 and 49 occurs continuously during the shredding process in which the vertical axis of rotation 31 rotates.

Therefore, the shredder according to the present invention as described above can be shredded to a size suitable for the purpose of use, using only one process and equipment using the principle of soft mills, such as mineral, rock, aggregate, construction waste, etc. This greatly reduces the time and cost, and at the same time has the outstanding effect of significantly reducing the installation area of the process equipment.
